Hi, I'm a little bit confused about what licenses I must purchase... I would like a setup litke this: DNS 1 server DNS 2 server Mail server Web server Expand server What licenses do I have to buy? For the mail server, do I need Plesk Expand Centralized Mail $99.00 and Plesk Centralized Mail Server Management License $399.00? I guess I don't need a Plesk 7.5.4 license? Is it correct that only the web servers (at the moment only one web server) need Plesk Expand Per Server License $199.00 ? On the DNS servers, is it correct that I only need to have Plesk Expand Centralized DNS $99.00 installed and that I don't need Plesk 7.5.4 and "Plesk Expand Per Server License" installed? Thank you very much in advance for taking time to answer my questions.
